Detailed Description
The embodiment of the utility model provides a through providing a steel sheet pincers clamp, solved among the prior art the inconvenient technical problem who adjusts in steel sheet position when performing the operation, realized the technological effect of conveniently adjusting the steel sheet position.
The embodiment of the utility model provides an in technical scheme for solving above-mentioned problem, the general thinking is as follows: the positioning hole on the pliers can block the sleeve on the steel sheet, and when the operator removed the pliers, the pliers also made the steel sheet produce through the sleeve and removed, conveniently adjusted the position of steel sheet, set up the dentate line, increased the frictional force of centre gripping.
For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.
Referring to fig. 1 and 2, a first embodiment of the steel plate clamping vise of the present invention is shown.
The utility model discloses a: the inner side surfaces of two clamping heads 11 of the pliers 1 are respectively provided with a toothed line 12, so that the clamping friction force is increased, and the steel plate 2 is moved; positioning hole 13 has been seted up to the medial surface of one of them chuck 11, positioning hole 13 is used for following the sleeve 21 joint on the steel sheet 2, just steel sheet 2 can be located between two chucks 11 of pliers 1. The steel plate 2 is provided with a plurality of sleeves 21, one of the sleeves 21 is selected to be inserted into the positioning through hole 13 of the forceps 1, the sleeves 21 and the positioning through hole 13 cannot be easily loosened due to certain friction force, when an operator moves the forceps 1, the forceps 1 also enables the steel plate 2 to move through the sleeves 21, and the position of the steel plate 2 is convenient to adjust.
The forceps 1 are bone holding forceps or reduction forceps. The bone holding forceps are used for holding bones during orthopedic surgery, and play a role in fixing and resetting. Two holding parts 14 of the pliers 1 are fixedly provided with racks 15 which can be meshed with each other. The mutually meshed racks 15 can lock the clamping state of the pliers 1, so that labor is saved.
The utility model discloses a steel sheet tongs's instructions for use: for example shin bone fracture patient, when doing the operation, need be at 3 fixed steel sheets 2 in fracture position, the operator uses the utility model discloses a steel sheet pliers clamp, detain a sleeve 21 on the steel sheet 2 with positioning hole 13 on pliers 1, corresponding cusp line 12 supports the surface of steel sheet 2, then the operator takes the portion 14 of gripping of pliers 1 and removes pliers 1, move steel sheet 2 to shin bone fracture position 3, the operator realizes the position of fine setting steel sheet 2 through fine setting pliers 1, confirm after steel sheet 2 reaches required position, fix steel sheet 2 at fracture position 3, remove pliers 1 at last, sleeve 21 roll-off pliers 1's positioning hole 13, the simple operation, the operation is efficient.
